ACRN v0.5 (Jan 2019)

We are pleased to announce the release of Project ACRN version 0.5.

ACRN is a flexible, lightweight reference hypervisor, built with real-time and safety-criticality in mind, optimized to streamline embedded development through an open source platform. Check out the What Is ACRN for more information.

All project ACRN source code is maintained in the repository and includes folders for the ACRN hypervisor, the ACRN device model, and documentation. You can either download this source code as a zip or tar.gz file (see the ACRN v0.5 GitHub release page or use Git clone and checkout commands:

git clone
cd acrn-hypervisor
git checkout v0.5

The project’s online technical documentation is also tagged to correspond with a specific release: generated v0.5 documents can be found at Documentation for the latest (master) branch is found at

Version 0.5 New Features

OVMF support initial patches merged in ACRN: To support booting Windows as a Guest OS, we are using Open source Virtual Machine Firmware (OVMF). Initial patches to support OVMF have been merged in ACRN hypervisor. More patches for ACRN and patches upstreaming to OVMF work will be continuing.

UP2 board serial port support: This release enables serial port debugging on UP2 boards during SOS and UOS boot.

One E2E binary to support all UEFI platform: ACRN can support both Apollo Lake (APL) and Kaby Lake (KBL) NUCs. Instead of having separate builds, this release offers community developers a single end-to-end reference build that supports both UEFI hardware platforms, configured with a new boot parameter. See Getting Started for more information.

APL UP2 board with SBL firmware: With this 0.5 release, ACRN now supports APL UP2 board with slim Bootloader (SBL) firmware. Slim Bootloader is a modern, flexible, light-weight, open source reference boot loader with key benefits such as being fast, small, customizable, and secure. An end-to-end reference build with ACRN hypervisor, Clear Linux OS as SOS, and Clear Linux OS as UOS has been verified on UP2/SBL board.

  • 2000 - After launching UOS with Audio pass-through, Device (I2C0) doesn’t exist in UOS DSDT.dsl

  • 2030 - UP2 fails to boot with uart=disabled for hypervisor

  • 2031 - UP2 serial port has no output

  • 2133 - The system will hang up and print some error info after boot UOS

Known Issues

1319 - SD card pass-through: UOS can’t see SD card after UOS reboot.

SD card could not be found after UOS reboot in pass-through mode.

Impact: There is no SD card after UOS reboot.

Workaround: None. The issue will be fixed in the next release.

1773 - USB Mediator: Can’t find all devices when multiple usb devices connected[Reproduce rate:60%]

After booting UOS with multiple USB devices plugged in, there’s a 60% chance that one or more devices are not discovered.

Impact: Cannot use multiple USB devices at same time.

Workaround: Unplug and plug-in the unrecognized device after booting.

1774 - UOS can’t stop by command: acrnctl stop [vm name] in SOS

After launching UOS in SOS by “acrnctl start” command, UOS VM failed to be stopped by “acrnctl stop” command.

Impact: Can’t stop UOS in SOS.

Workaround: None. The issue will be fixed in the next release.

1775 - [APL UP2]ACRN debugging tool - acrntrace cannot be used in SOS

There are no acrntrace devices “acrn_trace*” under SOS /dev.

Impact: acrntrace cannot be used in SOS.

Workaround: None. The issue will be fixed in the next release.

1776 - [APL UP2]ACRN debugging tool - acrnlog cannot be used in SOS

There are no acrnlog devices “acrn_hvlog*” under SOS /dev.

Impact: acrnlog cannot be used in SOS.

Workaround: None. The issue will be fixed in the next release.

1780 - Some video formats cannot be played in SOS

Video files with these encodings are not supported in the SOS: H265_10bits, VP8, VP9, VP9_10bits, H265.720p.

Impact: Cannot play those formats of videos in SOS.

Workaround: None. The issues will be fixed in the next release.

1782 - UOS failed to get IP address with the pass-through network card

After a network card is pass-through to UOS, it fails to get an IP address in UOS.

Impact: Cannot use network in UOS.

Workaround: None. The issues will be fixed in the next release.

1796 - APL NUC fails to reboot sometimes

After APL NUC boots to SOS, the “reboot” command sometimes fails to reboot the SOS.

Impact: Cannot reboot SOS.

Workaround: Power off and boot again. The issues will be fixed in the next release.

1991 - Input is useless in UART Console for corner case

Input is useless in UART Console for a corner case, demonstrated with these steps:

  1. Boot to SOS

  2. ssh into the SOS.

  3. use “./” to boot UOS.

  4. On the host, use “minicom -s dev/ttyUSB0”.

  5. Use “sos_console 0” to launch SOS.

Impact: Failed to use UART for input in corner case.

Workaround: Enter other keys before typing Enter.

1996 - There is an error log when using “acrnd&” to boot UOS

An error log is printed when starting acrnd as a background job (acrnd&) to boot UOS. The UOS still boots up normally, but prints: “Failed to open the socket(sos-lcs) to query the reason for the wake-up. Activating all vms when acrnd & to boot uos.”

Impact: UOS boots normally, but prints an error log message.

Workaround: None.

2267 - [APLUP2][LaaG]LaaG can’t detect 4k monitor

After launching UOS on APL UP2 , 4k monitor cannot be detected.

Impact: UOS hasn’t display with 4k monitor.

Workaround: None.

2276 - OVMF failed to launch UOS on UP2.

UP2 failed to launch UOS using OVMF as virtual bootloader with acrn-dm.

Impact: UOS cannot boot up using OVMF

Workaround: Use VSBL as virtual bootloader

2277 - [APLNUC]Launch UOS with 5G memory will hang 2 minutes

If launching UOS with 5G memory, there will be about 2 minutes hang.

Impact: Low UOS boot time performance.

Workaround: None.

2278 - [KBLNUC] Cx/Px is not supported on KBLNUC

C states/P states is not supported on KBL NUC.

Impact: Power Management states related operations cannot be using in SOS/UOS on KBLNUC

Workaround: None

2279 - [APLNUC]After exiting UOS with mediator Usb_KeyBoard and Mouse, SOS cannot use the

Usb_KeyBoard and Mouse After exiting UOS with mediator Usb_KeyBoard and Mouse, SOS cannot use the Usb_KeyBoard and Mouse. Reproduce Steps as below:

  1. Insert USB keyboard and mouse in standard A port (USB3.0 port)

  2. Boot UOS by sharing the USB keyboard and mouse in cmd line: -s n,xhci,1-1:1-2:1-3:1-4:2-1:2-2:2-3:2-4

  3. UOS access USB keyboard and mouse.

  4. Exit UOS.

  5. SOS access USB keyboard and mouse.

Impact: SOS cannot use USB keyboard and mouse in such case.

Workaround: Unplug and plug-in the USB keyboard and mouse after exiting UOS.

2338 - [UP2]Lost 2G memory in SOS when using SBL as bootloader on UP2.

After using SBL as bootloader to boot UP2, SOS only has 2G memory with 4G physical memory bank.

Impact: lost 2G memory in SOS.

Workaround: None. The issue will be fixed in the next release.
